Temporary Concrete Barrier Art. 704.05
d.Connecting Loop Bars (Note 2)
e.Packaged, Dry, Rapid Hardening Mortar or Concrete ............................ 1018 Note 1. Connecting pins and anchor pins shall be according to the requirements of ASTM F 1554 Grade 36 (Grade 250). Note 2. Connecting loop bars shall be smooth bars according to the requirements of ASTM A 36 (A 36M). CONSTRUCTION REQUIREMENTS
704.03 General. Precast concrete barrier shall be the F shape as detailed on
the plans.
704.04 Installation. The barriers shall be seated on bare, clean pavement or
paved shoulder and connected together in a smooth, continuous line at the locations provided by the Engineer. Except on bridge decks, or where alternate anchoring details are shown on the plans, the barrier unit at each end of an installation shall be anchored to the pavement or paved shoulder using six anchor pins and protected with an impact attenuator as shown on the plans. When pinning of additional barrier units within the installation is specified, three anchor pins shall be installed in the traffic side holes of the required barriers. Where both pinned and unpinned barrier units are used in a continuous installation, a transition shall be provided between them. The transition from pinned to unpinned barrier shall consist of two anchor pins installed in the end holes on the traffic side of the first barrier beyond the pinned section and one anchor pin installed in the middle hole on the traffic side of the second barrier beyond the pinned section. The third barrier beyond the pinned section shall then be unpinned. Barriers located on bridge decks shall be restrained as shown on the plans. Anchor pins shall not be installed through bridge decks, unless otherwise noted. Barriers or attachments damaged during transportation or handling, or by traffic during the life of the installation, shall be repaired or replaced. The Engineer will be the sole judge in determining which units or attachments require repair or replacement. The barriers shall be removed when no longer required by the contract. After removal, all anchor holes in the pavement or paved shoulder shall be filled with a rapid hardening mortar or concrete. Only enough water to permit placement and consolidation by rodding shall be used and the material shall be struck-off flush.
704.05 Method of Measurement. This work will be measured for payment in
feet (meters) in place along the centerline of the barrier. When the barrier is relocated within the limits of the jobsite, the relocated barrier will be measured for payment in feet (meters) in place along the centerline of the barrier. Anchor pins, except for the six anchor pins for the barrier unit at each end of an installation, will be measured for payment as each, per anchor pin installed.

704.06 Basis of Payment. When the Contractor furnishes the barrier, this
work will be paid for at the contract unit price per foot (meter) for TEMPORARY CONCRETE BARRIER or RELOCATE TEMPORARY CONCRETE BARRIER. When the Department furnishes the barrier, this work will be paid for at the contract unit price per foot (meter) for TEMPORARY CONCRETE BARRIER, STATE OWNED; or RELOCATE TEMPORARY CONCRETE BARRIER, STATE OWNED. Anchor pins, except for the six anchor pins for the barrier unit at each end of an installation, will be paid for at the contract unit price per each for PINNING TEMPORARY CONCRETE BARRIER. Impact attenuators will be paid for separately. SECTION 705. TEMPORARY STEEL PLATE BEAM GUARDRAIL
705.01 Description. This work shall consist of furnishing, erecting,
maintaining, and removing steel plate beam guardrail, including posts and traffic barrier terminals.
705.02 Materials. Materials shall be according to the following.

705.03 General. Construction of the temporary steel plate beam guardrail
and temporary traffic barrier terminals shall be according to the applicable requirements of Sections 630 and 631, respectively. After the guardrail and posts have been removed, the post holes shall be filled and tamped.
705.04 Method of Measurement. Temporary steel plate beam guardrail will
be measured for payment in feet (meters). The length measured will be the overall length of rail erected, measured along the top edge of the rail elements to the limits shown on the plans. The various types of temporary traffic barrier terminals will be measured for payment complete in place in units of each. The pay limit between the terminal and the adjacent guardrail shall be as shown on the plans.
705.05 Basis of Payment. This work will be paid for at the contract unit price
per foot (meter) for TEMPORARY STEEL PLATE BEAM GUARDRAIL, of the type specified, and at the contract unit price per each for TEMPORARY TRAFFIC BARRIER TERMINAL, of the type specified.
